Abstract

An anti-slip fastener remover tool includes a torque-tool body, a plurality of paired engagement features, and an intersection point. The plurality of paired engagement features that grips the lateral surface of the stripped fastener head is radially positioned around a rotation axis of the torque-tool body. The plurality of paired engagement features, wherein each paired engagement feature is offset by 30 degrees, comprises a first engagement feature and a second engagement feature. The first engagement feature and the second engagement feature each comprises a bracing section, a cavity section, and a connector section that are adjacently connected to each other. The cavity section of the first engagement feature is adjacently connected to the cavity section of the second engagement feature. The bracing sections of the first engagement feature and the second engagement feature are oppositely positioned of each other about the cavity sections of the first and second engagement features.

First claim

What is claimed is:

1. An anti-slip fastener remover tool comprises:
a torque-tool body;
a plurality of paired engagement features;
a plurality of intersection points, wherein each of the plurality of intersection points is a sharp point;
each of the plurality of paired engagement features comprising a first engagement feature and a second engagement feature;
a cross section for the first engagement feature and the second engagement feature each comprising a bracing section, a cavity section, and a connector section, wherein the bracing section is flat;
the plurality of paired engagement features being radially distributed about a rotational axis of the torque-tool body;
the bracing section and the cavity section being connected to each other by the connector section;
the cavity section of the first engagement feature being connected to the cavity section of the second engagement feature;
the cavity section of the first engagement feature and the cavity section of the second engagement feature being oriented towards the rotational axis;
the bracing section of the first engagement feature and the bracing section of the second engagement feature being oppositely positioned of each other about the cavity section of the first engagement feature and the cavity section of the second engagement feature;
an arbitrary paired engagement feature from the plurality of paired engagement features and an adjacent paired engagement feature from the plurality of paired engagement features being connected to each other through a corresponding intersection point from the plurality of intersection points;
a radial distance of the intersection point is larger than a radial distance of each point on the connector section of the first engagement feature on the same cross section as the intersection point; and
a radial distance of the intersection point is larger than a radial distance for each point on the connector section of the second engagement feature on the same cross section as the intersection point.

2. The anti-slip fastener remover tool as claimed in claim 1 , wherein a first angle between the first engagement feature is 30 degrees, and wherein a second angle between the second engagement feature is 30 degrees.

3. The anti-slip fastener remover tool as claimed in claim 1 , wherein a third angle between each of the plurality of paired engagement features ranges between 121-179 degrees.

4. The anti-slip fastener remover tool as claimed in claim 3 , wherein the third angle is 130 degrees.

5. The anti-slip fastener remover tool as claimed in claim 3 , wherein the third angle is 135 degrees.

6. The anti-slip fastener remover tool as claimed in claim 3 , wherein the third angle is 145 degrees.

7. The anti-slip fastener remover tool as claimed in claim 3 , wherein the third angle is 150 degrees.

8. The anti-slip fastener remover tool as claimed in claim 1 , wherein the connector section is a convex segment, wherein the connector section is oriented away from the rotational axis.

9. The anti-slip fastener remover tool as claimed in claim 1 comprising:
the torque-tool body being outwardly extended from the rotational axis to the plurality of paired engagement features.

10. The anti-slip fastener remover tool as claimed in claim 1 , wherein a first length ratio between the bracing section of the first engagement feature and the cavity section of the first engagement feature is 1:2.

11. The anti-slip fastener remover tool as claimed in claim 1 , wherein a second length ratio between the bracing section of the second engagement feature and the cavity section of the second engagement feature is 1:2.

12. The anti-slip fastener remover tool as claimed in claim 1 , wherein a radial distance of the intersection point being 4 to 12 times larger than a first-length for the bracing section of the first engagement feature.

13. The anti-slip fastener remover tool as claimed in claim 1 , wherein a radial distance of the intersection point being 4 to 12 times larger than a second-length for the bracing section of the second engagement feature.

14. The anti-slip fastener remover tool as claimed in claim 1 , wherein the bracing section of the first engagement feature and the bracing section of the second engagement feature are positioned offset of each other.

15. The anti-slip fastener remover tool as claimed in claim 1 comprises:
an attachment body;
the attachment body being centrally positioned around and along the rotational axis; and
the attachment body being adjacently connected to the torque-tool body.

16. The anti-slip fastener remover tool as claimed in claim 15 comprises:
the torque-tool body being inwardly extended from an outer wall of the torque-tool body to the plurality of paired engagement features;
an engagement bore; and
the engagement bore traversing into the attachment body along the rotational axis, opposite of the torque-tool body.
